WEATHER STRIP Filed Jan. :51, 1944 'z sheets-sheet 2 lf/m /15 i I INVENTOR. BY Geo/*564(/B/*af7xel Patented Aug. l, 1195i() UNITED STATES PATENT `FFICE WEATHER STRIP `George N. Brunker, saw-Lake city,r Utah `applicafina Januarysi, 1944,seria1No.1520,'24'1-7 My invention relates "to weather "stripping for doors and likeclosuresarid has ior its object to provide a weather stripping `which will be completely concealed yet which will he brought into contact withtlie door s'illatthei instantbf clos'- ing of the door and which will instantly raise upon i the slightest opening' of the door.

A further object is to provide a weather strip which will be set in a vertical s'lotcut along" the bottom of the closure or door which strip may be used inthe nest of doors without having an unsightly' appearance, yeta closure seal which'iwill close the maximum amount of space under the door.

A still further object is to provide a weather stripping which will` .be easily `and quickly installed and which may also be quickly andeasily` removedfor cleaning, yetwhich is positive its" sealing action.

A still further object is to provide a weather strip which when it is engaged with the door to seal under the door is so constructed that the lifting elements are entirely disengaged from the sealing medium and there is no spring tendency to lift the sealing strip but instead all of the spring pressure behind the sealing strip is engaged in pressing the strip down to engage the floor.

A still further object is to provide a new spring medium for holding a strip of weather sealing material into engagement with the door sill, frame, or when used on windows around the perimeter of the window or door frame.

These and other objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claim.

In the drawings:

Figure 1 is a face view of the door with the strip used to close the bottom opening thereunder showing the door closed.

Figure 2 is an end View of the lower free edge portion of the door.

Figure 3 is a section on line 3--3 of Figure 4.

Figure 4 is a view of the stripping removed from the door.

Figure 5 is a plan view of Figure 4.

Figure 6 is a face view of a portion of the felt strip showing the spring means for holding it down in place.

Figure 7 is a face View of the spring clip for holding the felt stripping in tensioned relationship with the floor or with the frame.

tendingupthereinand from edge to edgeofrthe door, "the-depth of :the slot beingsuincient to encompass the sea-ling `strip.`

The 'carrier plate 5 for the sea-ling strip "con` sist'sof an elongated strip of angularlyrformed metal or plastic having a horizontal portion '6 formed; therein with one-vertical portion?? extendin g down to overlap `the"ielt weathersealing strip 8 "and"withthevertical portion lil extending up substantially tothebottohffotheslot G and adaptedto rest againstonerside it' or the slot C. The vertical `portion e is `provided. with onehinged end bentat right anglesto forma se'c'uringilange orliug i IA which issecuredtothe `hinged end of the door by a screw or other suitablerneans. The other endF of the `vertical with a lip 'I3 adapted to` fit into a -recessiin a at plate id which is secured to the hinged edge of the door to support the entire device therein. These two ends provide the means for suspending the entire device in the slot C. When secured to the door in this manner the portions S and l of the plate 5 together with one side of the slot C form a channel in which the sealing strip 8 is carried and operated. The top edge of the sealing strip is provided with spaced apart metal angle braces or plates I 5 with each brace provided with a downwardly turned flange I6 through which a split rivet or solid rivet |"I is passed. The face of the plate 5 is provided with vertical slots i8 in which the rivets are operable and through which these rivets are extended with their large head outwardly of the plate. Attached to the braces l5 I provide elliptical springs i9 having their free ends engaging the horizontal portion of the plate 5 and these springs normally react against the top of the sealing strip 8 to hold it pressed against the door sill or floor under spring pressure. The bell crank levers L are pivotally attached to the plate 5 by pivots 20 at the bend of the lever and the top end of each lever is pivotally attached by rivets or pivot pins 22 to an angularly formed actuating rod 2| which is carried above the horizontal portion of the plate 5. The actuating rod 2| is carried spaced above the horizontal portion 6 by the bell crank levers and longitudinal movement of the actuating rod causes the bell crank levers L to be operated thus releasing the springs i9 to force the sealing strip down. toward the Iioor or sill of the door and if the member is moved its full amount of movement the strip engages the floor or sill forming the sealing means under the door. The actuating rod is held portion '9 is provided so that the bell crank levers are all lifted under the rivets by a coil spring S having one end attached to the vertical portion 9 by a hook 23 and the other end attached to the actuating rod 2l by a hook 24. The tension of the spring is set so that it normally holds the levers L lifted and therefore the sealing strip elevated fromthe floor. The means for causing the release of the springs I9 is provided by mounting a roller '25 in the bifurcated end 26 of the actuating rod 2| and this roller is mounted on a vertical shaft and is adapted to strike an operating plate 27 secured to the door frame by screws as shown in Figure 1 of the drawings. This plate 27 is preferably mounted on the door frame opposite to the side on which the door hinges are mounted for supporting the door and the plate is preferably formed with a slanting or ramp face so that the roller rolls over the face thereof movinglthe angle member longitudinally as it moves over the face of the ramp. This provides the quick action of the device for the instant that the door is opened sufiicient distance for the roller to leave the ramp face the springs elevate the weather sealing strip and it remains so elevated until the door is closed again at which time it is then lowered to sealing position just as the door is closing when the roller strikes the ramp.

Having thus described my invention I desire to secure by Letters Patent and claim:

A weather strip comprising a carrier plate of angular section having a` horizontal portion and vertical portions extending respectively upwardly and downwardly from the longitudinal edges of said horizontal portion, a sealing strip disposed underneath said horizontal portion and having means thereon in vertical sliding engagement with said downwardly extending portion, an actuating rod of angular section having a vertical portion above and substantially ln the plane of the downwardly extending portion of the carrier plate and an inwardly, horizontally disposed portion parallel to and above the horizontal portion of the carrier plate for actuating said sealing strip, bell crank levers pivoted at their angles to the downwardly extending portion of said carrier plate, upwardly extending arms of said levers being pivoted to said rod, longitudinally extending arms of said levers engaging said means on the sealing strip, said rod extending outwardly of the end of said carrier plate away from which said longitudinally extending arms extend and a spring mounted within the upwardly extending portion of said carrier plate and the horizontal and vertical portions of said rod, opposite ends 'of said spring being secured respectively to said rod and said carrier plate, said spring urging the outwardly extending end of the rod outwardly to thereby elevate the sealing strip.
